The terror mastermind was then shot at several times by the soldiers as he lay on the floor in his Pakistan compound, Matt Bissonnette claims.However, following the raid in May last year, US officials had said that the Seals shot Bin Laden only after he ducked back into the bedroom, because they feared he was reaching for a weapon.The book, entitled No Easy Day and written under the pseudonym Mark Owen, says the raiders found two unloaded weapons in the room and questions Barack Obama ’s motives for the raid.Special Operations Command spokesman Col Tim Nye said the retired Seal’s life could be under threat after his unmasking and jihadists on al-Qaeda websites have posted apparent photos of Bissonnette, calling for his murder.The book also reveals that, during the helicopter flight after the raid, one of the Seals in the cramped cabin sat on Bin Laden’s chest as his body lay on the floor.The Pentagon and the CIA are currently examining the text and may take legal action against the author.
